A least recently used (LRU) cache for Python. Pylru implements a true LRU cache along with several support classes. The cache is efficient and written in pure Python. It works with Python 2.6+ including the new 3.x series. Basic operations (lookup, insert, delete) all run in a constant amount of... Platforms: *nix

The NSS module is a fork from the nss_ldap package by PADL Software Pty Ltd.. This fork was done to implement some structural design changes. These changes were needed because there are some issues with the original design. See the documentation section for more details. The biggest advantages of... Platforms: *nix

django-templated-email is oriented towards sending templated emails intended for use with transactional mailers (ala mailchimp, silverpop, etc.), but currently comes out of the box with a backend class which uses django's templating system, and django's core.mail functions. Platforms: *nix

Class::Delegator is a Perl module that provides a subset of the functionality of Damian Conway's lovely Class::Delegation module. Why a subset? Well, I didn't need all of the fancy matching semantics, just string string specifications to map delegations. Furthermore, I wanted it to be fast (See... Platforms: *nix

Mako is a template library written in the Python language. It provides a familiar, non-XML syntax which compiles into Python modules for maximum performance. Mako's syntax and API borrows from the best ideas of many others, including Django templates, Cheetah, Myghty, and Genshi. Conceptually,... Platforms: *nix
